摘要:: 为满足发电厂、变电站对直流系统接地故障的查找和准确定位，基于差流测量法设计的定位仪，不仅能够检测直流系统绝缘电阻的大小，还能准确查找接地故障地点和范围。当直流系统某一点接地时，迅速报警排除，以防继电器误动、拒动，并能有效地避免二点接地给发电厂、变电站的直流系统造成更大的事故。为发电厂和变电站直流系统的可靠性、安全性，提供有效的检测和维护的手段

Abstract:: In order to meet the power plant and transformer substation to earth fault of DC system to find out and make a location accurately, pmpose the uneven flow examination method, design examined the measurement based on the uneven flow DC earth position finder. Not only it can measure DC system to the size of insulating resistance of grounded, but also look for the trouble place and range of insulating ground accurately. Prevent relay fmm move by mistake when one point grounding, also can prevent from two- point grounding cause heavy accident to DC systems of the power plant and transformer substation effectively. For dependability, security of the power plant and transformer substation with DC system, offer effective measuring and maintenance means
